BACKGROUND: The question of whether refractive or topographic changes are to be expected after eye muscle surgery is largely unanswered.
MATERIALS AND METHODS: Results of pre- and postoperative objective refraction, Pentacam (Oculus, Menlo Park, CA, USA), and visual acuity tests of 229 eyes are included in the present analysis. The examinations took place preoperatively, on the first postoperative day, and after 3 months.
RESULTS: After surgery on one or two extraocular recti muscle, there are significant changes in the cylinder (p < 0.001) on the first postoperative day, although values returned to normal after 3 months. Similar changes also appeared in combined operations of extraocular and oblique muscles.
CONCLUSION: The authors postulate that extensive patient education with regard to temporary changes in the cylinder is necessary, particularly when the extraocular muscles are involved, and that additional refraction and topography control can be useful postoperatively if visual rehabilitation is inadequate.
